We all know that optimizing JavaScript can be tricky. But what if I told you that some of the biggest performance wins don’t come from complex refactors or major architecture changes - but from tiny tweaks in the right places?

In this talk, we’ll go behind the scenes of JavaScript and the browser to uncover the hidden costs of everyday code. We’ll explore how the JavaScript engine actually executes our code, why certain patterns slow things down, and how to write code that works with the engine instead of against it.

Through real-world examples and surprising case studies, we’ll see how subtle changes - like reordering conditions, adjusting loops, and avoiding hidden pitfalls - can dramatically improve execution time and memory usage.

What you’ll take away:
✅ Practical optimizations that make a real difference in performance
✅ Common JavaScript patterns that secretly slow down your code - and how to fix them
✅ How JavaScript engines and browsers optimize execution under the hood
✅ Simple, effective techniques to make your code faster without overcomplicating it

If you've ever wondered why a seemingly innocent function is slowing down your app, this talk will help you understand what’s happening behind the scenes - and how to make your JavaScript fly.
